Weaving gd drill

[Dan Mac]

Hi. We have just bought a gd 4800m and mounted it on a mf 8480 we are having a issue with the hyd fan it fluctuates a good 200-300 rpm when we slow the flow of oil below 50% on the tractor it runs fine above 50% but to fast. I have had flow set at 43% and lifted drill up and down a good few time which settle the fan down and ran a constant 4800 rpm but not been able to do this again. Any ideas? Thanks

Hi Oliver not sure if it’s relevant but we had a similar problem on a vadersrad drill when we ran it on a Fendt or CAT
The fan was constantly hunting and wouldn’t settle
It’s a common problem and the solution is to fit a needle valve in the pressure line and bleed a small amount of oil into the return line

Probably more like 600rpm as fluctuates 300 above and below 4800.

We have some fluctuation on case and new Holland tractors with a caddy hopper
set the spool as priority
keep enough revs on the tractor
we find the fluctuation is when you pick up the drill as the rams demand more oil and the pump has to respond
it is less of a problem on the magnum and t7 hd due to there bigger pump
when we have high seed rates at higher speeds is when we need max air flow

Has anyone blocked coulters off on a gd to widen rows? For game cover drilling

Yes only run with every 3rd running to give approx 500mm row spacing in rape. Weaving can supply bungs that fit in the head. Works a treat.

Why? There is no yield benefit to wide row spacing in osr. I’m curious to know why folk do this with drills that have the intermediate coulters still fitted.

I fully understand why wider spacing is attractive for trash flow, reduced soil disturbance or to suit a cultivator setup on set spacings.

I used to do it.

I think the main benefit was being able to see a thicker row of cotyledons much sooner which meant it felt you had a crop earlier.
It's hard seeing a crop from 2kg/ha of seed, when most succumbed to slugs or beetles.

Thanks for that, it’s maybe not the drill for me then. I had an idea about putting a low disturbance toolbar in front of one to get a little 1 pass subsoil/ drill combi but that may not work either.

In that scenario I’d be tempted with a Vaderstad

There are shims. When you fit the discs you fit or remove shims until the discs are just touching.
The problem comes when the discs cut through a raised ridge of soil. The soil enters between the discs at the top of the opening and as the discs rotate and get closer together the soil gets nipped which stalls the discs.

Yes, was a right pain this year on ploughed and power harrowed ( was levelling ridge and furrow )

we've used our GD again this year despite a plan to sell it. It certain situations its tremendous. Had some bindweed in a no-till situation that the GD had no issues with at all and then the recent frosts it proved the perfect drill again.

I see that stone guards seem to be standard on a GD now. Weavings fitted some to our drill a couple of weeks ago, and although I have only drill one field since, it seems to have made a vast improvement where the soil is loose.

I recall my basis teacher saying with rape you want to be walking on one plant with every step with none in between. Any thicker and yield will be compromised. Some of our best crops (pre csfb) were from subsoiler mounted seeders

Fitted some to mine last autumn and completely agree, really does stop the blocking up and bulldozing when its been moved slightly.

Never been able to drill into anything that's been worked or even behind the Grange LD since we've had the GD without having to firm it up in front of the drill, drilled yesterday into land that had been LD'd and had a shallow pass Friday with the bullock rake (discs on front) and didn't block up at all.

I made these for my GD a few years back and Weaving came and took loads of pictures. Then launched there own stone guards.
One broke off recently and it wasn't long before that disc stopped. Just shows they work well!
